Climate Change: Simple, Serious, Solvable

Coming in 2027, free to read online

Climate change is simple: the physics is straightforward and inexorable. It's serious: continuing to burn carbon on a large scale would severely harm people and reverse centuries of economic progress. And it's solvable: we already know how to decarbonize the global economy, and we estimate that doing it will be far cheaper than the alternative, especially in the long run.

About the author

Scott Denning, smiling, beside a big globe covered in handwritten names

I've been teaching climate change to undergraduates for about twenty years: at Colorado State University, at Yale, and on Semester at Sea, teaching from a ship as it sails around the world. This book grew out of that course.
